That’s a funny way to put it, but after learning how  heat recovery systems work, I can see why someone would say that!
In many industrial facilities, a huge amount of heat is generated during normal operations and then simply released into the atmosphere. such as heating air, warming water, or supporting production processes. Instead of letting valuable energy disappear, the system puts it back to work.
What makes them seem “smart” is that they improve efficiency without requiring major changes to daily operations.
Aquifer Thermal Energy Storage (ATES) systems are frequently installed in industrial high energy need plants and processing facilities, as well as in large commercial buildings that require cooling and/or generate waste heat. The recovered heat can be used for example to preheat the supply air, to provide additional support to the boiler, or to feed other thermal processes.Another benefit is that it helps companies to be more sustainable. It is well known that the reusing of waste heat leads to less environmental pollution and better energy savings.. That’s one reason heat recovery systems have become increasingly popular as organizations look for practical ways to improve efficiency without sacrificing
